In this WP we aim to understand chemical variability of unsorted textile waste, develop and optimize textile shredding into fibers that can be further refined via aqueoues processes, create an analytical framework to assess dust identity and formation and finally to correlate process-property of shredded fibers.

This WP covers the development of refining processes to efficiently downsize textile fibers into nano-microscale, while understanding microplastic and fines formation and propose strategies to minimize and retain them. We study chemical and enzymatic routes to enable easier, and more controllable, fiber refining. We go further and we aim to understand water interactions and flow behavior of newly developed refined microfibers. Finally we correlate process-property-performance for refined textile fibers.

In this WP we test the portifolio of refined fibers in several applications in concrete, composites (including mycelium-based materials) and foams. We are developing computational setup for textile-based materials design within Processing-Structure-Properties-Performance (PSPP) framework. Then we will correlate fiber properties with performance in applications, while providing new fiber-based solutions leading to improved mechanical, thermal and acoustical properties and enabling higher fire-retardancy in construction materials.

In this WP we explore TEA and LCA tools to tackle bottlenecks in the process of refining textile fibers and during the manufacturing of fiber-reinforced materials.
